A path accommodation method for reliable ring networks with optical compression TDM

Very high-speed optical ring networks are recently developed for MAN (Metropolitan Area Network). In such high-speed networks, survivability is a very important issue since a single failure leads to a disastrous service interruption. In this paper, we propose a design method for the reliable ring network based on Optical Compression TDM. We assume a single failure; at most a single link fails a...

Blocking in Multiwavelength TDM

This paper examines the relative importance of wavelength conversion and time-slot interchange in improving the performance of multiwavelength time-division mul-tiplexed networks. It is shown that, in networks with a small number of wavelengths, each carrying a large number of time-division multiplexed channels, signiicant performance improvements are achieved by the introduction of time-slot i...

2 . Wdm - Tdm Switched Networks

ABSTRACT Multicasting in the optical layer has gained significant importance in the recent years due to several factors. Most of the research work in this area concentrate either on minimizing the number of wavelengths required to meet a given static demand or on multicast route selection algorithms to achieve efficient utilization of fiber bandwidth. Very few significant research has been foun...
